Our laboratory can offer ferrite content measurements
through a light optic microscopic with our phase analysis
program PicEd Cora. Ferrite content measurements are
performed through automatic picture analysis.
In the sample for microscopy different phases are
separated by colour and luminosity (or contrast) by using
an etching solution suited for the alloy in question.
After the etching the different phases are coloured in
PicEd Cora, where you afterwards obtain the area for each
phase presented as a percentage.
Part of our ferrite content measurements takes place
during procedure testing of ferritie-austenitic (duplex)
materials, where requirements according to SS-EN 13445
are prescribed.
Ferrite content measurements are also performed on
materials such as austenitic stainless weld metal. |
